A study was undertaken to identify the tasks which make up the day of library/media specialists in Mississippi. A jury of library/media specialists and professional administrators reviewed tasks identified by the national model and the Mississippi State Board of Education and developed a questionnaire which identified 21 selected library/media related tasks and other tasks frequently assigned to instructional personnel. The instrument was mailed to 300 randomly selected Mississippi media specialists who were asked to identify their time per task in percentage increments to reflect a total of 100% of their working day. Questionnaires were returned by 101 media specialists, or 34% of the sample. The results of this study are compared to a similar study of Tennessee library/media specialists and to teachers in the NASSP (National Association of Secondary School Principals) Model Schools Project in 1977. The results indicate that Mississippi public school media specialists spend more time "keeping study hall" (19.28%) than any of the other 21 items. "Working with students or teachers in the instructional program" ranked second (10.27%). Following a discussion of the implications of the study, the paper identifies 23 technical and administrative tasks for which media specialists are responsible. (THC)
